Are there any differences in parts from the 1992-1993 civic to that of the 1994-1995 civic besides the obvious O-rings and use of R-12 for the later model civics?

Are the lines the same? Do older model civic a/c lines fit on a 94-95 civic?

Any feedback is appreciated.

If you're thinking about converting it over, I'd suggest to replace the drier as well. Fittings and oil in the system are the main differences. R-12 uses PAG oil if I'm correct and R134 uses Esther oil which is compatible for both, but you must remove as much of the PAG oil from the system or it will clump up into a jelly paste and clog the system.

I have a 95 civic and I accumulated parts for a/c from a 93 civic.

1) WIll the 93 parts fit on my civic with no problems?

2) if they fit, can I use the 93 parts with r134 even though they are not recommended for its use?

MrDX

Ok... Let's assess whatcha doin... Are you
1. replacing a bad a/c system
2. putting in a/c to a car that never had it

1st... Honda uses like 3 different a/c conpressors. Sans, Hayden, and Mitsubishi, If i'm correct all the lines are different... same length, just different ends. Getting a reman compressor isn't that expensive.
2nd... I know they make a new kit for civics that didn't come with a/c... this kit is complete and goes for about $600-$700.
3rd... If you're having a/c troubles... take it to a location to check so they can determine exactly what's the trouble.... I've seen alot of Hondas with bad low pressure switches that don't allow the a/c to come on for a $30 screw on part.

I have a 93 civic which has the r-12 system and i tried to put a 94 civic condensor in. The r-12 lines did not seal properly when i tried to connect it to the 94 condensor so i know for sure that the 94-95 civic a/c condensor and compressor will not work with the 92-93 parts.

I am putting a/c on in a car which never came with it.

I am not trying to mismatch parts. I just want to know if the 93 parts I have will fit flush all together on my 95 civic. If they do, then I will charge it with r-12. If they dont then I need to find me some 94-95 a/c parts.

MrDX

Well... to do this, I'd recommend getting the appropriate compressor for the year and engine model (due to possible fitment issues) and go from there... also make sure to get the a/c cluster on the dash.

KayOs

Have the r-12 compressor, and my vehicle came pre-wired for a/c. I'll try to fit these parts on.

na.. R12 is like $3 an ounce and your car will use about 18 ounces max and is still around. But then again R134A is like 50cents

So if you have a '93 AC system it will be R12 , You will need a new reciever/drier since they dont like being open and air is your enemy when it comes to AC service. and installing it will be easy and no problems.

But if I was you I would go and find a R134A system and if you get it used you have to take out all the oil out and check the helm or honda to see how much new oil you will need to put back in the system and make sure you use the right weight oil.
also if your going to get a used one go and buy a new Reciever Drier from honda and when you get it make sure it is sealed.. and when you instlal it.. make sure you dont leave it open the dessicant in it will absorb the air and will start to contaiminate your system. same goes for the oil.
and the lines are different too.. the R134A uses barrier hoses since the pressures are higher than R12
And the oil.. PAG /POE= 134A and Mineral Oil = R12

hey batuking, i replaced my condensor with an r-134 and i have a r-12 system but it doesnt seal completely tight, but i still put in a screw and screwed it in. Its been like that for 7 months WITHOUT freon, so when i find the right condensor and replace it, do i have to buy a new drier? sorry if what i wrote doesnt make sense

MrDX

yes...it is highly recommend that everytime the a/c system is opened to replace the drier, then have the system evacuated from the moisture.

Yes you will need to replace it.. the hoses on the R12 are smaller than the R134A so thats why your condensor will not fit.

R134A has barrier hoses..

here is what you do.. get all the parts together and make sure you use R134A approved O-ring. Now to keep the seals working do this.. get some mineral oil to lube the seals when installing the lines. then replace that Drier unit since you left it open for so long its not going to do its job anymore. Then you go and vaccum the system and make sure it holds vaccum thats a good way to check for a leak. Then depending on machine you can do oil injection or just install the oil (pag Oil for honda )in the compressor and alittle bit in the condensor.

Can you mismatch evaporator units? I think I have an evaporator from a 95 civic but my a/c parts are from a 93 civic.?

So what years had what chemical stuff?
EDIT: never mind. R-12 = later models, correct?
